net/mlx5: fix CPU socket ID for Rx queue creation

The default CPU socket ID was used while creating the Rx queue and this caused
creation failure in case if hardware was not resided on the default socket.

The patch sets the correct CPU socket ID for the mlx5_rxq_ctrl before
calling the mlx5_rxq_create_devx_rq_resources() which eventually calls
mlx5_devx_rq_create() with correct CPU socket ID.
